The Chat 50 will continue to receive power through the USB cable, eliminating the need to use the Chat 50’s external AC power adapter. 13. Repeat steps 1 through 12 for any additional devices you will be using with your Chat 50. To ensure optimal sound quality, you need to customize the Chat 50’s audio settings for every application and device you will use. Refer to the tuning procedures in the Optimizing Sound Quality section below. If you need assistance, click the Help button in the Chat application, refer to Chapter 3: Using Chat 50 Configuration Software, or contact ClearOne technical support using the contacts provided on the inside cover of this manual.
OPTIMIZING SOUND QUALITY
For optimal sound quality, you must adjust the Chat 50’s audio settings for each device and application you will be using as described in the procedures below. > Note: The volume settings in the Chat software are synchronized with the Windows volume settings. Changing the volume using the Chat software or the buttons on the Chat 50 also changes the volume settings in Windows. Conversely, changing the volume settings in Windows also changes the settings in the Chat software.
Using The Chat Application With Pre-Defined Device Settings The pre-defined device settings available in the Chat application will provide good sound quality for many of the most popular devices used with the Chat 50. If you used the procedure in the previous section to configure the Chat 50’s settings for one of these devices, test the sound quality before performing any additional tuning. If you are satisfied with the sound quality, no further adjustments are necessary.
Using A Third-Party Application If you are using the Chat 50 with an application other than Chat−such as Cisco Communicator or Skype−ClearOne recommends using the tuning wizard or audio configuration controls in that application to adjust audio settings. If the application does not have a tuning wizard or audio settings, use the Chat application to tune audio settings for optimal sound quality as explained in the next section.
Using The Chat Application 1. If not already open, start the Chat application. 2. For the Chat software, click the My Devices button and select the device you want to tune (select the Other or All option if your device/application is not listed), then click the Apply to Chat button. 3. For external hardware devices, connect the device to the Chat 50 using the connection diagrams on pages 13 through 16. 4. Adjust the speaker and volume settings on the external device or in the application to 50% (half volume). 5. Click the Advanced button to display the pre-defined audio settings for the device you selected in step 2. Use the USB Audio section of the screen to tune applications; use the Line Audio section to tune external hardware devices connected to the Chat 50’s 3.5mm port. > Note: In the Advanced screen, adjusting Microphone Level under USB Audio changes the Chat 50 microphone volume for USB applications, while adjusting the Output Level under Line Audio changes the microphone volume being sent to the device connected to the Chat 50’s line audio jack. Likewise, adjusting Speaker Level under USB Audio changes the Chat 50 speaker volume, while adjusting the Input Level under Line Audio changes the speaker volume being received from the connected device. 6. Place a call using the device or application. Land lines provide the best audio for tuning purposes. 7. Ask the person on the other end of the call to count from 1 to 10 in a normal voice. While the person is counting, click and move the Input slider in the Chat application until the caller’s voice can be clearly heard. Repeat as needed to find the optimal speaker volume for the device.
Chapter 3: Using Chat 50 Configuration Software 13 8. While the caller is still on the phone, count from 1 to 10 in a normal voice. Ask the caller if they can hear you clearly. Click and move the Output slider until the caller can hear you clearly. Repeat the test count as needed to find the optimal microphone volume for the device. 9. Click Save to Database to capture the optimized settings. The Add Settings to Database dialog appears. Enter appropriate name in the Model field, then click the Save to Database button. 10. The optimal audio settings for the device or application are now ready for use. Repeat steps 1 through 9 for any additional devices and applications. To switch between audio settings for different devices and applications, click the My Devices button, select the desired device or application, then click the Apply to Chat button. The audio settings are instantly applied for the chosen device or application.

Chapter 3: Using Chat 50 Configuration Software 23 Advanced Settings: Audio Settings The Audio Settings screen (Figure 3.11) displays the current audio settings and allows you to change them (Figure 3.11). You can also create custom audio settings for a particular device (see the Advanced Screen: Database section for more information).
FIGURE 3.11 Advanced Settings: Audio Settings
Available audio settings include: • USB Audio: Controls Chat 50 audio settings when it is connected via USB to your computer. Use the mute buttons to mute the microphone or speaker on the Chat 50. Use the sliders to adjust the microphone level and speaker level. Speaker and microphone level adjustments made in the Chat software will automatically change the speaker and microphone volume levels in Windows. • Line Audio: Controls line-in and line-out audio levels when the Chat 50 is connected to devices through its 3.5mm jack. These controls are grayed out (unavailable) when there are no devices connected to the 3.5mm jack. Use the input slider to adjust the level of the incoming audio to the speaker; use the output slider to adjust the level of the outgoing audio to the far end. • Speaker: Controls speaker settings when the Chat 50 is connected to devices through its 3.5mm port: • Normal: USB audio and line-in audio from the 3.5mm jack are mixed through the Chat 50 speaker. • Video Mode: Routes audio from the far end of the conference call to the connected video conferencing device or application instead of the Chat 50 speaker. USB audio is routed through the Chat 50 speaker. Ensure that the Chat 50 is properly connected using the appropriate accessory adapter cable (sold separately). See figure 2.19 for the connection diagram. • External Speakers: Routes both USB and line-in audio sources to external speaker(s) connected to the Chat 50’s 3.5mm jack. In this mode, the Chat 50 functions as a microphone only. This is useful for video conferencing to ensure the audio and video originate from the same point in the room. • Line Echo Cancellation: Enables line echo cancellation, which eliminates echo when the Chat 50 is connected to a telephone. Telephones route audio from the mouthpiece to the earpiece so that you can hear yourself talk, which causes feedback when using a speaker phone.
> Note: Enabling line echo cancellation may cause audio problems if the Chat 50 is not connected to a telephone.

28 Technical Support: 800-283-5936 Chapter 4: Using The Chat 50 28 CHAPTER 5: MAINTENANCE
CARING FOR YOUR CHAT 50 • Follow all warnings and instructions marked on your Chat 50. • Unplug the USB 2.0 cable from the Chat 50 before cleaning. • Unplug the power supply from the wall outlet before cleaning. • Do not use liquid or aerosol cleaners. Use a damp cloth moistened with water to clean the outside of your Chat 50 and power supply.
TROUBLESHOOTING POOR SOUND QUALITY If you experience poor sound quality, check the following list for solutions to common issues. • Ensure the Chat 50 is connected to your computer, start the Chat application, then verify, test, and adjust the audio settings as needed to obtain good sound quality. Or select an appropriate ClearOne pre- programmed device and click Apply to apply the settings to the Chat 50. If the issue remains unresolved, the third-party device or application may be responsible for the poor sound quality. Refer to the device or application documentation, or contact the manufacturer’s technical support for assistance. • Verify that all cables are properly and securely connected. Refer to the appropriate connection diagrams in Chapter 2: Getting Started of this manual for more information. • If your Chat 50 is connected to a USB hub, the USB hub must be connected to an external power source. • If you have another USB device (such as a digital camera) connected to your computer on the same USB bus as your Chat 50, Windows may generate the error message “USB Controller Bandwidth Exceeded.” In this case, you must move the other USB device to a separate USB bus. The Chat 50 is a high- performance USB device that requires sufficient bandwidth to function properly. • Some USB cameras that use audio drivers are automatically assigned by Windows as the default audio playback device (even though the camera doesn't have a speaker). In this case, disconnect all USB devices (including your Chat 50), reconnect the Chat 50 to the USB bus first, then reconnect the other USB devices. This allows Windows to properly select the Chat 50 as the default audio playback device. If you are unable to resolve the problem, please refer the support pages on our website, or contact ClearOne Technical Support:
